Questions and Answers for TUSA Lead Battery For Diver Propulsion Vehicle:
I have a Tusa SAV-7 dive scooter. There is no lead dive plate under the battery but it is still too negative. Battery in it weighs 19.2 pounds. Is there anything I can do to add buoyancy to the unit. Guessing around 4 pounds. I have heard about a buoyant vest but unable to find.
